About Section 232
Section 232 of the Trade Expansion Act of 1962 lets the President restrict imports that threaten national security. The standing Section 232 actions cover steel (HTS chapters 72–73) and aluminum (chapter 76) articles, copper (chapter 74) articles, and a growing list of downstream "derivative" products in other chapters (for example certain fasteners and fabricated parts). Core metal articles can be 50%, while some derivatives are taxed only on metal content under the applicable annex. Because it is product-based, Section 232 generally applies regardless of where the metal was made, and it stacks on top of the base duty and any Section 301, temporary surcharge layer or AD/CVD tariff — see how tariff stacking works. For the combined number, run the tariff calculator; coverage is defined in the Section 232 proclamations and product annex.
